These alternative terms are all linguistically more restrictive than "educational technology" in that they refer to the use of modern tools, such as computers, digital technology, electronic media, networked digital devices and associated software and courseware with learning scenarios, worksheets and interactive exercises that facilitate learning. However, these alternative names individually emphasize a particular digitization approach, component or delivery method. Accordingly, each conflates to the broad domain of educational technology. For example, m-learningemphasizes mobility, but is otherwise indistinguishable in principle from educational technology.

History, theory, types of media and information and communication technologies, and usage settings[edit]

The origin or etymology of e-learning is contested, with the e- part not necessarily meaning electronic as per e-mail or e-commerce. Coined between 1997 and 1999, e-learning became first attached to either a distance learning service[5] or it was used for the first time at the CBT systems seminar.[6] Since then the term has been used extensively to describe the use of online, personalised, interactive or virtual education.

Bernard Luskin, an educational technology pioneer, advocated that the "e" of e-learning should be interpreted to mean "exciting, energetic, enthusiastic, emotional, extended, excellent, and educational" in addition to "electronic." [3] Eric Parks suggested that the "e" should refer to "everything, everyone, engaging, easy".[4] These broad interpretations focus on new applications and developments, as well as learning theory and media psychology.

Moore et al found "significant variation in the understanding and usage of terms used in this field" and pointed to "implications for the referencing, sharing and collaboration of results."[2] In usage, e-learning is an extremely significant (but incomplete) subset of educational technology. As such, various aspects of e-learning are discussed in that article.
